For regression testing of our production application, we difference images produced by different version of our program. We've noticed that the font spacing on out charts has slight differences when run on different PCs. The environments on these PCs are closely controlled (e.g. all 32 bit XP SP3) to reduce the chances of differences being introduced other than by the software. We are looking for any settings that we should use to minimize machine-to-machine output differences. We are currently using ImageExporter.SaveToFile() using the PNG file output; we could use another one if that were better. The fonts we're using are garden variety (e.g. Ariel). I'd appreciate any suggestions.
Thanks
